   Returns the current &quot;event loop time&quot;, which is the time the event loop
   received events and started processing them. This timestamp does not change
   as long as callbacks are being processed, and this is also the base time
   used for relative timers. You can treat it as the timestamp of the event
   occurring(or more correctly, libev finding out about it).
